Touchscreen & Raspberry Pi Cooled Housing

This is an alternative to the excellent Ender 3 Touchscreen Case & Holder for Raspberry Pi by Tronnic.
Wishing to use a Pi 4 I did not feel the fan blowing on the back of the Pi pcb would provide adequate cooling. I have designed a back to the case, that fitted with a small centrifugal fan, ducts cooling air into the space between the Pi and TFT to take heat away fron the heatsinks.

I used a 24V 4010 fan, but these are also available in 5v and 12v models to suit your setup.
Heatserts are used to secure the fan.

NOTE: Assembly requires that the front housing, with Pi and TFT installed, be installed in the support frame before installing the case back and clip.
